HIBERNATE SETUP

Setup

The first thing we need to do is to set up the development environment. We will be using the "standard layout" advocated by many build tools such as Maven. Maven, in particular, has a good resource describing this layout. As this tutorial is to be a web application, we will be creating and making use of src/main/java, src/main/resources and src/main/webapp directories.
We will be using Maven in this tutorial, taking advantage of its transitive dependency management capabilities as well as the ability of many IDEs to automatically set up a project based on the maven descriptor.

NOTE:

It is not a requirement to use Maven. If you wish to use another technology to build this tutorial (such as Ant), the layout will remain the same. The only change is that you will need to manually account for all the needed dependencies. If you use Ivy to provide transitive dependency management you would still use the dependencies mentioned below. Otherwise, you will need to find all the dependencies, both explicit and transitive, and add them to the projects classpath. If working from the Hibernate distribution bundle, this would mean hibernate3.jar, all artifacts in the lib/required directory and all files from either the lib/bytecode/cglib or lib/bytecode/javassist directory; additionally you will need both the servlet-api jar and one of the slf4j logging back ends.

Save this file as pom.xml in the project root directory.
